This study examined the extent to which mora deletion (phonological analysis), nonword repetition (phonological memory), rapid
automatized naming (RAN), and visual search abilities predict reading in Japanese kindergartners and first graders. Analogous
abilities have been identified as important predictors of reading skills in alphabetic languages like English. In contrast
to English, which is based on grapheme-phoneme relationships, the primary components of Japanese orthography are two syllabaries—hiragana
and katakana (collectively termed “kana”)—and a system of morphosyllabic symbols (kanji). Three RAN tasks (numbers, objects,
syllabary symbols [hiragana]) were used with kindergartners, with an additional kanji RAN task included for first graders.
Reading measures included accuracy and speed of passage reading for kindergartners and first graders, and reading comprehension
for first graders. In kindergartners, hiragana RAN and number RAN were the only significant predictors of reading accuracy
and speed. In first graders, kanji RAN and hiragana RAN predicted reading speed, whereas accuracy was predicted by mora deletion.
Reading comprehension was predicted by kanji RAN, mora deletion, and nonword repetition. Although number RAN did not contribute
unique variance to any reading measure, it correlated highly with kanji RAN. Implications of these findings for research and
practice are discussed. 相似文献

文物翻译需要译者在不同文化框架下进行思维转换,通过概括、增/减译和变译等翻译技巧将原文信息传递给译文读者。山西大同云冈石窟为世界文化遗产,其现有的洞窟简介英译值得商榷。译者在翻译洞窟简介文本时,不仅要勘正译文语法错误,还应在英语和汉语文化框架下灵活转换,同时在英译过程中适当运用概括、增减和转变原文信息等技巧,以便国外游客更有效地理解石窟造型和佛教文化。 相似文献

由于英、汉两种语言在语法、词汇和修辞上的差异，有些词语或句子成分，在英语中是必不可少的，但若搬到译文中去，就会影响译文中的简洁与通顺。因此，为了避免重复，使译文更符合汉语的习惯，在翻译过程中有除赘的必要。 相似文献

In the present study, we investigated the relationship between general auditory processing, Chinese tone processing, English
phonemic processing and English reading skill in a group of Chinese-English bilingual children with a tonal L1 and Korean-English
counterparts with a non-tonal L1. We found that general auditory processing contributed to variance in English word reading
skill for Chinese children after controlling for Chinese tone and English phoneme deletion skill. English phonemic processing,
on the other hand, explained a significant amount of unique variance in English reading for Korean children after controlling
for general auditory and Chinese tone skill. These findings suggest that Chinese children relied more on general auditory
processing in reading English, whereas Korean children relied more on phonemic skill in reading English. These findings are
discussed in terms of the impact of cross-language differences in bilingual reading acquisition. 相似文献

Background: Imbalance in cholesterol homeostasis may lead to gallstone disease. Apolipoprotein B is sole component of low-density
lipoprotein and plays an important role in cholesterol metabolism. The present study was carried out to explore the association
of APOB 3′ VNTR, exon 26 XbaI and signal peptide insertion/ deletion polymorphisms with gallstone disease. 214 ultrasonographically proven gallstone patients
and 322 healthy, age and sex matched controls were taken for the study. Genotyping was done using PCR followed by polyacrylamide
gel electrophoresis for VNTR and insertion/ deletion analysis. For APOB XbaI polymorphism PCR product was digested with XbaI restriction enzyme, followed by agarose gel electrophoresis. All statistical analyses were done using SPSS v11.5. Higher
repeat alleles of APOB 3′ VNTR polymorphism were more frequent in gallstone patients than in controls. Alleles with more than 57 repeats were present
only in patient group. Long (L) alleles with repeat higher than 49, were significantly higher (P=0.000; OR=3.705, 95% CI 2.577–5.326) and medium (M) alleles were lower (P=0.000; OR=0.406, 95% CI 0.304–0.542) in patients than in controls. To nullify the effect of gender, data was further stratified
into male and female population. APOB 3′ VNTR, L alleles were imposing risk and M alleles were protective in both male and female population. APOB
XbaI and insertion/deletion polymorphisms were not found to be associated with the gallstone disease. Longer alleles of APOB 3′ VNTR occur more frequently in gallstone patients, and may be an important risk factor for the development of gallstone
disease. APOB XbaI and signal peptide insertion/deletion polymorphisms may not be contributing to the risk for gallstone disease. 相似文献

现代化、工业化、城市化、市场化与科技的发展,一方面极大地改善了人类的物质生活,使之逐步走向富裕。同时,现代化的进程所带来的负面影响,诸如工具理性泛滥、市场拜物的盛行、战争的严重灾难、环境的严重污染与资源枯竭、精神疾患蔓延等,又直接威胁到人类的生存,使之处于一种非美化的生存状态,而这种社会上美与非美的冲突也已经渗透到高校的人文教育方面。文章从高校教育缺失内容出发,指出加强育人才是解决现在社会发展一系列矛盾的关键,这不仅是高校存在的价值,更是一个国家民族的根基所在。 相似文献

合成生物学是利用工程化的思想来设计和构建新的生物基因组,是近年来的研究热点。近年来,对原核细胞支原体天然小基因组进行从头合成并进一步设计与构建最小基因组,对原核模式生物大肠杆菌基因组的不断删减及全基因组密码子简约化设计与人工合成测试,以及对真核模式生物酿酒酵母基因组人工设计与合成测试都取得了很大成功,极大地促进了我们对生命的理解。我国的基因组的设计与工程化构建方面的研究虽然起步较晚,但近年来取得了国际瞩目的成果。基因组的设计与构建为深入了解生命起源与进化,并为进一步构建具有强大应用功能的新型生命体奠定了基础。 相似文献
